Hi,I would connect my EvoPrimer STM32F107V by using USART TX,RX on connector to a DB9 RS232 to communicate with a Hyperterminal program for a PC. To do this I used the demoSerial_USART_2 http://www.stm32circle.com/projects/project.php?id=133compiled for my target, but on Hyperterminal I see only strange charactares. Why ?Thanks in advances,Gzuccaro
Hello,Try to change the baud rate on your terminal.regards,
Hi,I have tried to change baudrate but it didn't worked: I have seen the same behaviour.Gzuccaro
Did you adapt the signal voltage ?The Primer Rx/Tx are 3V/0V signals, and PC signals are +12/-12V.You need a TTL/RS232 adapter. Take a look at the web to purchase it or design it (with a MAX232 for example).
