I am using nucleo491re MCU to communicate with tca9537 GPIO-Expander . I want to use GPIO for on/off in tca9537 based on i2c . IN tca9537 I have four resister 1. Input(read) address( 0x01) 2.output (read/write) address(0x02) 3.polarity address( 0x...
Hi everyone, Trying to create an eeprom API based on the AT24CM01 ASIC chip. I got the Byte write working no problem, however the IC is capable of doing sequential writes up to 256 bytes. The way I am doing this is setting the 'RELOAD' value within t...
Hello Community,I'm using GT911 with STM32F746 over I2C. I have noticed some time it stucks when multi touch is used (very few times in single touch as well). Upon debugging I noticed a change of voltage level of Interrupt pin.In working state, INT p...
Hi.I work on BMS. I want a master-slave topology. I want to use 300 slave cards and 1 master card. This BMS is for automotive. I check ST MCU. I guess, The card should be 10-bit I2C. Because I want 300 Slave cards. So, Can you Help me this subject? W...
I am trying to implement LCD and AMS5812 Sensor on I2C3 Bus,But AMS5812 I2C sensor is holding the I2C bus and preventing further scanning STM32F407G Discovery board. /*-[ I2C Bus Scanning ]-*/ HAL_UART_Transmit(&huart2, (uint8_t *)StartMSG, s...
After inspecting blocking I2C functions from HAL libraries I found that apparently I2C blocking functions don't return "HAL_TIMEOUT" status if timeout is reached during I2C transfer. The following function does the work of verifying whether timeout w...
Hello, I am using the embedded coder support package in simulink to interface with my onboard MEMS acceleration sensor (LSM303AGR) on my STM32F411VET discovery board. I could successfully connect and run simple LED program through USART2 on simulink ...
My setup is as follows: I have a NUCLEO-H563ZI with an STM32H563ZIT6 and I am communicating through I2C with the 6D IMU, ISM330DCL. Moreover the ISM330DCL is on the STEVAL-MKI182V2.My I2C-bus is very confusing. First I get everything set up exactly a...
Hi, I am trying to read data from a sensor over I2C, I am using pin B8 as the SCL line and B9 as the SDA line. The code worked once and after reading the data from the sensor, pin B9 got stuck pulled low. I terminated and reloaded the debug session a...
Hi,I have a problem with an 24LC64 EEPROM, it is not a bad chip because i have tried 2 on diffrent boards. I am using the STM32G0B0 This are my I2C settings:I am using this libary : https://github.com/nimaltd/ee24/blob/master/ee24.cI only get 255 ba...
