Hi allI'm working with an stm32f4 and I have a question about current consumption on stop mode, on the pin PC1 I have a external pull up 10k connected to 3.3v, before stop mode what is the best mode to avoid PC1 consume 0.33ua ? Right now I have put ...

Hi,I'm trying to use spi on STEVAL-IDB008v2 board I want to wire spi flash dev board, after reading the documentation I'm not sure but if I want to have spi on bluenrg2 I have to desolder R64 and R63 resistors ? EDIT : it's seem 1-2sel and 3-4sel are...

Hi all, I'trying to explore steval board with BlueNRG2 chip, I'm working on BLE_SensorDemo project, works nice, right now I wan to develop my owm file, so far I've developped a library for SPI flash.I've added my header in Inc folder et my source fil...

Hi all,I'm trying to acheive STOP mode on my stm32f405, but ir's hard to come down 1mA as de datasheet say < 100uA. So to explain my project :- STM32F405 Freertos- 3 i2c capteur (power of captor is managed by switch)- 1 spi flash nand w25n01My clock ...

Hi all, I'm trying to test STEVAL-IDB008V2 board with wise studio and BLE_SensorDemo project I can compile and flash with RF-Flasher.So for now I'd like to add my own service, the basic example privde 2 services - Acc service- Env serviceI'm trying t...

Ok so if I put PC1 in Analog mode no current pass through my external resistor when I'm in stop mode ? Bad news for me in stop mode I have 480ua current and I hoped that the problem would come from PC1, so my issue coming from another part.

Thanks for the reply @QSHAO.1 So I have to solder wire ? There is no built in solution on dev board ? This strange all ST dev board I had, have jumper or something, for this kind of situation.So far, I'll try with wire. Keep you in touch

Yes I'll try it.Did I understand the documentation correctly when I said that in stop mode it is not necessary to stop the device clocks ? For example if I used usart1 I don't have to call__HAL_RCC_USART1_CLK_DISABLE

I've not checked yet the signal from my oscilloscope, I'll do it.My device configuration is : - pull up resitor 10k on SDA and SCL - 3 devices on the I2c line LSM6DSO32, LIS2DU12 and BMP384 - I2c reading/writing code come from stm github, for example...

Question about current consumption on pin

Use SPI with STEVAL-IDB008v2

How Wise Studio work????

STOP mode F405 hard to come down 1mA

STEVAL-IDB008V2 add service error
