USB CDC how to increase speed (baud rate) ?
Hello everyone,I am working on a signal analyser device, which needs to transmit data serially as fast as possible (idealy 1Mbaud/s).I am doing the following loop to transmit: uint8_t buf_high[1] = {124}; // '|' uint8_t buf_low[1] = {48}; // '0' ini...
Resolved! Configure AF GPIO register using 11U STM32F446RE
Hi, i came across a program to config alternation function for SPI GPIO port A. GPIOA->CRL |= (11U<<20); // PA5 SCK AF output push pull GPIOA->CRL |= (11U<<28); // PA7 MOSI AF output push pull What does the 11U means? i know its somethin...
Resolved! STM32G474RET6 ADC over work voltage
I have a project , used regular conversion ADC1 Vrefint Channel and Temperature Channel, and used injected conversion ADC2 extern Channel(ext.CH1 and CH2).ADC2 CH2 connect 2000mV voltage , CH1 is changed. If CH1 over 3.6V,the CH2 conversion is error...
