STM32F072RB discovery board The STM32 in slave mode is to be used to read sensor data at every 2 second interval by an ESP8266 master through I2C. I am using the HAL library for this.

The I2C interrupts were enabled and HAL_I2C_Slave_Receive_IT() and HAL_I2C_Slave_Transmit_IT() functions were called. The slave can receive and transmit the data only once and then it pulls the SCL line low disabling further communications. I have tr...

Resolved! Is there a replacement for the STM32F4 discovery kit?

I am starting a project which involves a CMOS camera. I only need to take still images, not video. I would greatly prefer being able to use a microcontroller over an SBC or FPGA. STMicro used to have an STM32F4 with a camera daughter card, but it app...
