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 there, I'm using the STM32H7 to talk to a CS2000 clock chip over I2C. I'm using interrupt mode.I'm just trying to read the chip's ID register for starters. Despite the CS2000 ACKing the first 'setup write' byte, it won't write the second byte (wit...
i was thinking if there is a way i could generate 4 timers phase shifted by 90 degrees wrt each other so that i could use them to generate 2 pwm signals (on each timer using asymmetric mode) . can this be done? if not, is there any other way i could ...
i want to read ADC MCP3425 digital data using i2c communication with Stm32f103rb nucleo-64 board . For programming of nucleo-64 i used arduino ide. 1] Is it possible to modify default setting of MCU clock ? 2]what is the default setting of i2c clock ...
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...
