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

stm32f103 has 20kb RAM. 8 ch * 64 pixel * 24bits/pixel * 1/8 byte/bits = 1.54kb With a 16bit timer you need about 3kb.

codes of the keyboard to the mapping table. The key scan codes were not straight from 112...123 for F1..F12, as can be seen in the attachment. I take the requirement for a more condensed representation in the monitor for decimal and Hex into account, thanks for your comment, Moby ;-) The requirements

during debugging of baud rate difficulties in a timer controlled bitbanging software serial of an STM32F103RBT ARM Cortex M3. If you wish a line feed carriage return in the monitor, your MIC has to send the #13 #10 chars. @Moby: which is the reason for better having a more condensed representation

[STM32] Crossreference ChipID - Device (EN / DE)

people! Having had some trouble finding a decent source of information regarding the Chip ID on STM32 µCs and the Flash/Sram size, here's an appeal to gather known and tested information you all might have come across. As an example for what information should be in, at the end there's a snippet of

STM32 GCC problem writing to flash bank 2

the 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

C++ STL and STM32

Hi, I have a problem with the C++ STL on the STM32. The following code works as expected on my hardware (chinese board with STM32F103..) [c] int main(void) { char Line[512]; std::list<std::string> *pHistory; pHistory = new std::list<

Hello Hase, I agree that I strain the stack a bit, but out of the 64k RAM in the STM32, I have less than 8k for .data and .bss sections. The remaining 56k are used for heap and stack. The initial stack pointer is set to the end of RAM and the heap grows upwards from the end of the .

yagarto example project for STM32F100C4 chip

Hello, I'm new user of the yagarto tool-chain. The example project for STM32F103 works well for me. I'm going to move to simpler target chip STM32F100C4. It should be the Low density Value Line device (STM32F10X_LD_VL). I'm not sure how to setup-up project or how to modify linker script and start-up code for that chip. Please can someone send me a example project for STM32F100C4 for yagarto or any advice how to do it please?

STM32 GDB / OpenOCD Commands and Initialization for Flash and Ram Debugging

incorporated in a make file for flash vs ram building for this mcu, if this matters of course. mcu: STM32F103VET6 I am using Eclipse Helios with Zylin Embedded CDT, Yagarto Tools and Bins, OpenOCD .4, and have an Olimex ARM-USB-OCD-H Jtag adapter. I have already configured the ARM-USB-OCD and added

initializing OpenOCD I used the following command in Eclipse (The board config file references the stm32 mcu and was found in the OpenOCD installation as an example): "openocd -f interface/olimex-arm-usb-ocd-h.cfg -f board/stm32f10x_128k_eval.cfg". When I run this within Eclipse everything appears

Interrupt handler in C++ File?!

You cannot do that as part of a class. I don't know the STM32, but my guess is that interrupt vectors are known by their global name, so they cannot be established using C++ name mangling. This also implies they cannot be hidden with in a class (class members

a register is reserved for a base address - but details are missing. Maybe "fPIC" works for certain other architectures only. So if anybody knows something....? Axel

how can i debug code in ram ?

Sourcery 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.
