Posted on April 28, 2016 at 15:20Dear all, I have problem transferring relatively large block data (>= 600 bytes) over USART. All blocks smaller than 600 bytes can be sent successfully from MCU and the host at the other end receives that correctly. ...

Posted on December 10, 2015 at 14:50Dear all, I am using a STM32F103VEH micro-processor. I intend to put the processor into sleep mode and configure it so it will wake up by receiving any interrupt. I use the following code:   uint32_t tmpreg = 0;  ...

Posted on October 07, 2015 at 15:53Hi all, I am using a STM32F103 chip where USART1 and USART2 are connected to Smartcard units. I have tried to communicate to the Smartcard by first sending a reset signal (according to ISO 77816 definition) and the...

Posted on September 04, 2015 at 19:08Dear all, I want to use TIM1 CH3N  to drive a buzzer with different frequencies. I have tried to program TIM1 on channel 3N as below (the corresponding pin is already configured as AF_PP at 50 MHz): void buzz(uin...

Posted on September 04, 2015 at 09:23Hi all, I have implemented a simple routine to drive a buzzer. The routine will enable a timer and will toggle state of the pin connected to the buzzer at different frequencies. The buzzer code is: void buzz(uint...
