Posted on June 06, 2018 at 13:42Hi!I found setting up an external interrupt in an STM32F103 to be a little bit hard. What is the sequence of to do's? I can find information fragments about the EXTI and NVIC, scattered through the reference manual an...
Posted on June 08, 2018 at 11:20Hi,I have a problem to achieve max. sampling rate of 2.4 MSPS(12 Bit) @168 Mhz Clock, AHB2 Bus is running at 84 MHz and ADC Clock = 42 MHz.Any idea why I get just sampling rate of 1.4 MSPS and not maximum sampling r...
Posted on June 08, 2018 at 15:25Hello,I try to have a periodic wakeup of my chip.I read the RTC documentation, and I tried to setup the RTC periodic wakeup unit.I managed to get a periodic interruption but I don't understand why the counter is not c...
Posted on June 08, 2018 at 15:04 Hi, I've got a weird problem with I'd like some advice on. I've configured an STM32F334 as a I2C Slave, and am using Sequential IT driven operation with variable length packets (e.g. first byte received is length ...
Posted on June 07, 2018 at 21:58Hi,i am beginner in stm32I configured SWCLK AND SWDIO for Serial Debugging.Can I Change SWCLK and SWDIO as input and output at runtime?If Change the MCU is RESET or Not?
Posted on June 08, 2018 at 13:26hi, I am a beginner of stid135, I had a problem when I tried to configure stid135 to output TS. I used PRBS11 as the data source of a dvb modem to modulate a dvb-s signal, then to use development board STiD135 NIM_B22...
Posted on June 08, 2018 at 09:15I use STM32F103CBT6 for my project. This is something trouble this time. One of VDD pins of MCU is broken and not have connection to pcb. Another three pins are fine. Would MCU work fine if i not resoldering it and wo...
Posted on June 07, 2018 at 16:26Hello everyone,I am currently working on a traveler counting system that is based on a PIC18 and I would like for network link reasons to make a serial link (RS232), in fact, a new standard of transport, to put in dis...
Posted on June 08, 2018 at 11:47HiI'm trying to read ADC 6 channel but I got very strange result 60 or 4095 not the right one...Any help are welcome what I'm doing wrong. I need without DMA if possible without?main initstatic void MX_ADC_Init(void...
