STM32 Changing PWM Duty Cycle in interrupt handler

aSma>> wrote in post #4970691: > The stm32f103 timer has only 16 bits. I assumed I needed to provide my data as uint32_t as the example from the SDK ( /STM32Cube_FW_F1_V1.4.0/Projects/STM3210E_EVAL/Examples/TIM/TIM_DMA/Src/main.c ) declares

said, I didn't look into DMA before as my initial analysis was it > would need too much RAM. stm32f103 has 20kb RAM. 8 ch * 64 pixel * 24bits/pixel * 1/8 byte/bits = 1.54kb With a 16bit timer you need about 3kb.

OOCD with the STM32F103

Good day every one! I'm using the STM32F103 series in an embedded application, together with OOCD. Now the 1st setup: STM32 Evalboard by KEIL with the STM32 in a 64 Pinout and 64 K Flash (STM32F103R8T6) Amontec-JTAG-Key OOCD r423 and r717

Worked just great :-) The 2nd setup: STM32 now in my embedded app. and with 48 pinout 64 k flash (STM32F103C8T6) Amontec-JTAG-Key OOCD r423 and r717 Didn't work! :-( Well it did work sort of, that is, OOCD finds the two JTAG-Devices inside the µC and than 'hangs': The output of OOCD with debug = 3:

STM32F103VET6 und CH340R

I have a problem with my PCB. I recieved it a few days ago and it is already completly presoldered. If i connect it via USB-TYPE B to my pc it is showing me nothing in device menager.... The CH340G should be visible to be able to programm it via usb.... If i connect it via micro-usb unknown device is popping up. But that does not help me :). I have added the schematic. Hope someone can help me.

Which microcontroller to use and how?

you want something larger then I would recommend any ARM based microcontroller, for example the STM32F103 series which is available in different sizes). Regarding your current monitor: If you measre the current between power supply and voltage regulator then you measure the current consumption of

recommend to control the MAX5217 for the best results and more accurate? price is not important. the STM32F103 ?

STM32 ADC & DMA corrupted Values

Are you using an STMF103C8xx or STM32F103CBxx? I am asking because the web is full of negative reports about fake products with wrong data transferred by DMA.

STM32 HAL Delay too slow

Hi, I recently started with an STM32F103C8T6 on a bluepill board. I am using SW4STM32 on Windows 10. When writing a program that blinks an LED on PC13 with the standard peripheral library and implementing my own SysTick_Handler and

own firmware. I give you a hint, how to do: https://www.mikrocontroller.net/attachment/316790/STM32F103C8T6.ZIP Just have a look into it - and use what you want if you are interested. btw: the binary in this archive should also work on a blue-pill board. W.S.

STM32 GCC problem writing to flash bank 2

code in the second sector. I was able to debug this code (using optimization level 0) on an STM32F103xD (which has 384K of flash) when unoptimized code was about 160K. However, the code has now grown to 220K unoptimized, 130K at optimization level 's'. Therefore I have been able to finish debugging

flash upgrade functionality on optimized code. To allow for future growth I have upgraded to an STM32F103xG, which has 1M of flash configured in two banks. I have been able to continue debugging, and I can run the flash upgrade into either bank when in debug mode. However, if I build the code at optimize

how can i debug code in ram ?

G++ Lite Edition ,openocd and jlink on ubuntu 10.04.for the flash run,it work well.the MCU is STM32F103VE I download the start up code and link script from the web.I modify the link script to something like this: .isr_vector : { . = ALIGN(4); KEEP(*(.isr_vector))

I did test with STM32F103C8T6 ($3 chinese board, known as blue pill). The only thing I had to do is to write my linker script to put everything in RAM, then: 1. Put the jumpers at BOOT0 & BOOT1 pins to boot from RAM.

GDB issue (cortex-M3)

ARM-eabi 2009Q1, OpenOCD (different but rather up-to-date versions), Amontec JTAGkey, FTDI-drivers and STM32F103CB for the tests. Debugging from Eclipse works as expected (well, at least what I expected/needed). A little bit of additional information can be found in the readme.txt.
