The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Im debugging with an ST-LINK J9357 debugger chip in Eclipse's debug workbench . I've been over the debug configurations many times and cannot find an error. Once i start the debug and it shuts off the connection there isn't even an error box detailin...
Hello everyone,I am trying to interface my STM32F401RE with OV7670 camera. I have set the input clock for the camera from the MCO output of the board at 8MHz. Because my board is not provided with DCMI, I have to explicitly implement the communicatio...
Hi ST Community,I hope someone can help me with the following problem:I am working an a Nucleo STM32F303K8 (with Cube MX and True Atollic) and would like to produce some PWM signals from it. So TIM1 and TIM2 are producing PWM just exactly how I would...
LiPo battery ratings is 3V to 4.2V.Any reference circuit than please share.I want to learn exact calculation for ADC.There are various values of RAIN mention in table 63 of datasheet.Should i use same values for Resistor Divider?How much counts i can...
I would have thought the text on it would prove to be meaningful but apparently according to every search I have tried it is not. Thanks for your help.
I have a device that must execute precompiled functions which are copied to a place in RAM. Function calling:PLC_main = (pFunc_main) 0x30000001; PLC_main();Compied function: PLC_1 0x30000000: 4811 .H LDR r0,[pc,#68] ; ...
Using STM32F0308C on a custom board. When I read the temperature sensor I am getting 1765 and the TS_CAL value is 1778.Supply voltage is 3.3V, VREF_INT is 1524 and I am reading 1525 on the internal reference. So I assume I must apply a 1524/1525 corr...
1. Is it ok to set 3.3V as a divider output which goes to ADC pin?2. The external voltage at VDDA pin (We have given the same VDD as VDDA) show some fluctuations while ADC monitoring so can you suggest the best possible way to monitor battery voltage...
Dear community,I am using the STM32F103C8T6 32 bit ARM Cortex M3 microcontroller.In Section 9.2.1 in the reference manual (GPIOx Control Register Low) it says that the reset value is 0x4444 4444 (which means all pins are floating inputs).However, whe...
Hello everybody!I try to configure TIM2 to interrupt in the range of 100Hz ... 1kHz. Strangely, the actual frequency I set is divided by 2: if I configure the timer to run at 1000Hz, it will run at 500HzTIM2 configuration:void System::InitTimers() ...
