I use this:void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef * htim) { if (htim->Instance==TIM2) // Tarda 2.17 us en llegar aqui, AQUI DIBUJO EL BUFFER, EN HSYNC { if((m<56)) { for (h=0;h<16;h++){} //10 ORIG, AQUI DAMOS ESPACIO PARA FONT PORCH HAL...

The FMPI2C master of STM32F446 module extends (stretches) the acknowledge (ACK) bit with random delays

The FMPI2C master of STM32F446 module extends the clock of the acknowledge bit with random delays from a few microseconds to a few milliseconds. That happens quite frequently w/o causing an issue, but sometimes the SCL line remains forced low by the...

ADC input and GPIO output on the same pin

Does anybody have any experience in using exactly the same pin as an ADC input and a communication GPIO (out), as two alternating functions? Would it be possible to switch between them? If so,can the GPIO drive the small capacitor that is typically n...
