STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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() ...
Looking at the datasheet for STM32F20xxx ADC; if I run the ADC at 30MHz and use the minimum sample time of 3 (100ns), the input sample capacitor will not be fully charged even with zero source resistance. The input spec is 6K and 4pF, if you take th...
