I wish to configure my STM32 MCU (STM32G071RB) as an I2C slave device, and support I2C burst-write and I2C burst-read, in a similar manner to many I2C slave devices:(usually the RA value is incremented after every DATA byte)The I2C receive/transmit f...
Hello,While I was tracking an issue on I2C bus, I found something that seems to be unconsistent in HAL file stm32l4_hal_i2c.c1 - routines I2C_WaitOn_____UntilTimeout() are called after locking the bus with __HAL_LOCK(hi2c) macro2- these routines upda...
Hi, i'm developing a project on STM32H7A3IIK6 [cortex M7] and i'm having a problem using the I2C peripheral with the ST HAL functions. I've initialized the peripheral and enabled the Event and Error Inpterrupt with TX and RX DMA and, sometimes, i hav...
Hello All,We are using STM32G041F8P6 in our project. This IC will be programmed through I2C/USART and we will be using System Memory for booting(internal flash).As per the datasheet:At startup, the boot pin and boot selector option bit are used to se...
I have been using a stm32f051 as a slave on i2c1 without any problem. Then I started to use it as a master on i2c2 at the same time. This caused the communication on i2c1 to fail with varying frequency. I have been using the i2c drivers with interru...
Could someone please help me to convert My tested arduino code on STM32, now using HAL apis to drive same code :#include <Wire.h>int16_t X, Y, Z = 0;const uint8_t STK8321 = 0x0F;const uint8_t startRegister = 0x02;void printAcceleration() { byte accel...
This is a super super weird one.My device (STM32F401RC) uses the latest HAL libs vs STM32CubeIDE. USB is configured as device-only, CDC.It works *perfectly* until i also enable one of the I2C peripherals (HAL, config'ed as I2C slave) and send/recv I2...
I am struggling to find working examples to work with FreeRTOS in an interrupt mode.I use the function HAL_I2C_Slave_Transmit_IT() This enables the interrupt as well as setting up the data.It works to a point, then the remote Master send a Nak and 8 ...
I made an I2C communication between STM32U585 uC to an I2C EEPROM and it worksI do the following but if I remove the HAL_Delay(10) or minimizes it to less than 10msec things are not working well, the second call I2C_Master_Transmit fails.Is there's ...
I am looking for an interrupt based replacement for HAL_I2C_IsDeviceReady. I am implementing a EEPROM library for M24256 I2C Serial EEPROM in a FreeRTOS application. The call HAL_I2C_IsDeviceReady relies on polling for many milliseconds to perform ...
