Hello! I am trying to enable SPI communication through the SPI3 interface on an STM32F103ZFH6. I am aware that pins PA15 and PB3 are used for JTAG and SWJ, but I have disabled both using:GPIO_PinRemapConfig(GPIO_Remap_SWJ_Disable, ENABLE); There is n...

The problem was that the series resistor on the clock line was faulty/not soldered properly.

Thank you for clearing things up!. At least now I can be sure to look at the hardware more carefully. It is probably a bad soldering job, since its a ballgrid package.

Ok, tried this and I attached the output from my logic analyzer. As you can see the data 0xAA is sent over the MOSI line, but the clock pin is low always.I have checked my board, the pin is not shorted to ground. while(1) { GPIO_WriteBit(SC16_CS_PO...

I used CUBE to generate SPI3 code, but I didn't see anything I am not doing. I am using the exact same modes and speeds, enabling all necessary clocks and disabling JTAG and SWJ. Only thing I noticed that seemed odd was that I2C1 was indicated to con...

All GPIO clocks A-G are enabled, AF clock is enabled as well.I checked GPIOB->IDR and GPIOB->ODR after setting PB3 to RESET(0) and after SET(1).I got, after setting PB3 to low:GPIOB->IDR[3] = 0GPIOB->ODR[3] = 0and after setting PB3 high:GPIOB->IDR[3]...
