Stm32 i2c busy flag problem

Hi, Due to flexibility and ease, I would like to build and flash my GD32F130C6T6 project with Platformio. I tryied using a genericSTM32F103C8 with Flash size and Ram size updated to match the one of GD32F130C6T6, but did not work. It did compile and flash, however it doesn’t run. With Keil uVision the firmware runs without problems. What should I do, any suggestions? Thanks in advance!

OK,I found the problem. Flag I2C_ISR_TXIS did not get because the device on the i2c did not respond to the sent address. Need to convert the device address to 7 bits.

Mar 01, 2019 · I2C scanner for STM32f10x series. I2C scanner is fairly simple, yet fast and effective way to find whatever device you put onto I2C bus. Some devices (boards) comes with clear designation on the PCB, some with misleading designation – address is shifted to the left, so for example OLED display typical address is 0x3C/0x3D (depends of address selector jumper), but shifted to the left by 1 bit ...

The other problem with ChibiOS I2C driver that I found reading RM is clearing of CR1_ACK flag and setting of CR1_POS flag depending on the size of transaction. Namely I2C on STM32F4 (and F1 AFAIK) requires that for receiving of 2 or less...
I have carefully looked at the MEMSTOLCD example, and used it as a base for my I2C operation. I have also initialised the RCC, GPIO and I2C, however i am still having problems when using the application in Circle OS. The problem occurs after the START is generated, the program sticks in the while(!I2C_CheckEvent(I2C1, I2C_EVENT_MASTER_MODE ...

2、空闲时scl跳变,这是一个i2c的错误信号,但是stm32却会认为这是一个s,所以scl跳变会导致busy置位,而且不会像sda跳变那样会产生一个p中断。 如果在单主的情况下,你可以为I2C的S做一个超时,超时了就软复位I2C就可以,当然最简单的方法还是空闲时关闭I2C(PE ...
Jul 23, 2020 · Next on the I2C read flag RAM_SWAP_BUSY = 1 , OSD map register(0x0C) = 2. And the value of this flag RAM_SWAP_BUSY always remains equal = 1. (log.txt lines 52, 263, 306) In the Blim driver, this flag is read in a loop = 1000 times. And the program continues its execution. But! RAM_SWAP_BUSY = 1 is always.
My last comment is to the bit bashing and troubles around - the line is usually pulled down by STM32, if you don't follow the proper flag handling (by improper testing and clearing flags, you can ''hide'' one event followed by another, and I2C gets stuck in the previous state, holding the SCL down).

I managed to take on all the above relatively quicker with respect to my deadline requirements, until i realised that I took almost 6 days upon this stupid problem of interfacing an I2C based commonly used RTC chip - PCF8563....man this was the greatest shocker!!
Hi, everybody. I have STM32-LCD and I'm trying make work it with MOD-RS485-ISO on UEXT2. So, if I understand correctly, i must send command to MOD via I2C to start work and then work with it like RS232?

Jul 26, 2019 · When the memory is sending data out we have a big problem. L=0V but H=1V. Many people write the software so the computer drives the pin high. The I2C bus was built for the only pull up is a resistor and no silicon pulls up. The EEPROM does not pull up. A pull up resistor pulls up. 5K to 3.3V and 2.2k to ground makes about 1 volt. I would do 1 ...
The secret to your success is the STM32CubeMX software, which is available only on windows (groan). To start things off, we're going to get basic I2S audio into the STM32. I started with the SPH0645 I2S You could also add a flag in the compilation step of your makefile to prevent this.

Feb 07, 2012 · I2C is a transaction-based bus. Each transaction ahs a start and stop condition and an arbitrary number of byte transfers in-between. If you're the only I2C master ont eh bus, the oly one who can start a transaction is you. The busy bit only indicates whether a transaction start has been detected and no transaction end has happened yet.

One of the most common solutions to solve this problem is I2C, or inter-integrated circuit. I2C is a serial communication bus which uses two wires – one clock and one [bidirectional] data line. It is a master-slave protocol, meaning there must be at least one master and at least one slave on the bus.

Jul 16, 2017 · I think(but I may very well be wrong) the hd44780 library requires an active R/W capability and may use the busy status. Certainly the test program does. If you only write to the display some other libraries will work correctly with R/W grounded and no checking of the status flag.

I2C answers some of the problems of SPI including no multi-master mode, no slave flow control and more pins to use. But in terms of speed, SPI is still faster due to its push-pull driver compared to the open-collector driver for I2C. Configures APDS-9960 over I2C and waits for gesture events. Calculates the direction of the swipe (up, down, left, right) and displays it on a serial console. To perform a NEAR gesture, hold your hand far above the sensor and move it close to the sensor (within 2 inches). Hold your hand there for at least 1 second and move it away.

Um nun die Nutzung des I2C Moduls einfacher zu machen, werden eine reihe an Wrapper Funktionen definiert. Mit I2C_start wird die Start-Condition auf dem Bus erzeugt und die Adresse des Slaves gesendet, damit befindet sich der STM32 im Master Mode.

We have two registers with the same name. One we write to control the I2C module, the other one we read from to get the status of the I2C module.

When we write to I2CMCS register, it configures the I2C controller operation. 24 I2C_Send7bitAddress(macI2Cx, MPU6050_SLAVE_ADDRESS, I2C_Direction_Transmitter);//7bit slave address + read/write (0write,1 read) 25 . 26 I2CTimeout = I2CT_FLAG_TIMEOUT; 27 . 28 /* Test on EV6 and clear it */ 29 //从机地址发出之后,等待 BUSY, MSL, ADDR, TXE and TRA flags标志位

Sep 26, 2012 · I'm seeing problems with the Chibios I2C driver on the STM32F4 when there is noise on the I2C data line. If the noise reaches a certain level, the processor "locks up" because it is continuously servicing an I2C interrupt that never get cleared. I was able to reduce the likelihood of lockups by adding the following code to 解决stm32 i2c接口死锁在busy状态的方法讨论 关于stm32的i2c接口死锁在busy状态无法恢复的现象,网上已有很多讨论,看早几年比较老的贴子,有人提到复位mcu也无法恢复、只有断电才行的状况,那可是相当严重的问题。 * This parameter can be one of the following values: * - I2C_FLAG_DUALF: Dual flag (Slave mode) * - I2C_FLAG_SMBHOST: SMBus host header (Slave mode) * - I2C_FLAG_SMBDEFAULT: SMBus default header (Slave mode) * - I2C_FLAG_GENCALL: General call header flag (Slave mode) * - I2C_FLAG_TRA: Transmitter/Receiver flag * - I2C_FLAG_BUSY: Bus busy flag ...
