STM32F072RbT6 I2C1 not working.
Hello,I am using STMCUBEMX 5.2.1 to initialize the configurations of my STM32F072RBT6. My application requires the use of i2c1 since i2c2 is already occupied on our board by a pressure sensor. However, it seems to me that i2c1 is not working (i.e. th...
Hi i am using stm32f746zg nucleo board and i want to establish communication between two CAN modules where CAN1 should transmit and CAN2 should receive the msg but its not happening dont know why ..can anyone help me with the code ..?
here is my codevoid can(void){ CAN_TxHeaderTypeDef TxHeader; uint32_t TxMailbox; uint8_t usr_msg[10]={'h','e','l','l','o'}; TxHeader.DLC=2; TxHeader.RTR= CAN_RTR_DATA ; TxHeader.IDE= CAN_ID_STD; TxHeader.StdId= 0x65; if(HA...
STM32F4xx I2C slave not working
I'm currently trying to setup a STM32F4DISCOVERY Board with the STM32F407VGT6 chip as a I2C slave. Somehow the controller doesn't send any ACK bit after the address was received. I've tried with the General Call function as well.Here is my initialisa...

Hello everyone!I'm want to use the internal reference voltage buffer of the mcu stm32g431kb as input with comparator, but when i checked the reference manual they say VEREFBUF must kept disabled because no VREF+ pin in 32 pin package!!I don't want th...
stm32f103 spi communication with ad7730 random wrong number
I am communicating with ad7730 (24bit adc) using atm32f103ZCT6. I try to read one of the registers of the adc but each time I receive a random wrong figure. The strange thing is that while debugging using serial wire (STLINK) everything is perfect an...
