Posted on March 22, 2017 at 11:55Hi,I am using 3 USART in my code, But I faced a one ridiculous problem with them.USART2 configured on interrupt and working fine I have No problem with this one. I Initialize the USART3(POL) first and send some data ...
Posted on March 22, 2017 at 19:46I'm having trouble getting a powerStep01 configured to run in step clock mode on top of a Nucleo F411RE. Mostly configured as required, but as soon as I try to enable it (hardstop) it throws an OCD and drops out of s...
Posted on March 19, 2017 at 18:08Hi,I have a strange behaviour with the stm32F746 RTC.I use a 32768-Hz crystal (I have verified with the scope that it is running).I initialise as indicated in the following code, but the time register is incremented ...
Posted on March 22, 2017 at 17:03Hi everybodyI want to make a smartcard with sm32. I know stm32 has smartcard interface using Uart peripheral. however all the documents I have seen, used stm32 as smartcard reader. is it possible to use stm32 as a sm...
Posted on March 21, 2017 at 15:35STM32F437In the main code I set ARR to 0xFFFF and PSC to 21000-1, a long count at a leisurely pace. After the timer counts a bit I enable an external event with my function generator. In my ISR experiment I immediate...
Posted on March 22, 2017 at 16:03In STM32F427?the ADC noise is horrible when the mcu access the sdram or fpga by fsmc at the same time.I want to know Whether this issue has been solved in STM32F7?If done?I can use STM32F7 to solve the ADC noise.#stm...
Posted on March 22, 2017 at 14:42hello dear forum, I dont use https://www.mikrocontroller.net/part/STM32F103 https://www.mikrocontroller.net/articles/JTAG pins for debugging ( I use USART1 for program loading ) can I use these pins as output port...
Posted on March 22, 2017 at 14:12STM32L0 LSI oscillator stops after a system reset, like software reset or watchdog reset, but LSI is not stopped by exit from standby. What is the difference between exit from standby and other system reset?
Posted on March 20, 2017 at 20:12 Hi. I'm reading 1025 index float lookup tables where the last item is for looping the data. The input to the function is a 32-bit phase number which is converted to 10-bit for indexing and a 22-bit rest for in...
