I’m using an ST‑LINK V3 Minie with an STM32F100RBT6B Discovery board (which also has an STM32F103C8T6), and it works perfectly. However, when I connect the same ST‑LINK V3 Minie to my custom board that uses the same STM32F100RBT6B chip, it fails to c...
Posted on May 23, 2018 at 16:45Hello, I am trying x-nucleo-plc01a1. but there are two jumpers (J5 and J11) on the board. I can't find any document to describe how to use them. Anybody can help?thank you.
Hi. I'm trying to read data from W25Q64 flash memory.These are my connections:And these are my SPI and RCC and GPIO settings:And these are my functions and main code:Using W25Q_ReadID function, i could read device ID.But i can't read data stored on d...
Hi,On STM32G071CBU6, when PB15 is used as CC2 with DBCC2 shorted to CC2, does the ROM bootloader ever drive PB15 as SPI2_MOSI, or does the CC/dead-battery own the CC2 pin and that path always takes priority?This detail is critical for our design beca...
I am using an STM32L433 to pass I2S audio from a bluetooth receiver (BT401) to a PCM amplifier (MAX98357A) using DMA.I have got it working, but there is an issue with the clock. It plays the audio fine for a few seconds and then there is some interf...
Hi there,I'm starting to use the NUCLEO-H533RE board to evaluate the H5 device family.RM0481 has some errors on the PLL configuration:Fig.55 on page 461 shows a VCO range 0 between 128 and 560 MHz, but the description of bit 5 of register PLL1CFGR (p...
Hello,I configured TIM1 as shown in the attached image: Everything works as expected I am controlling an inductive load which oscillates heavily after the PWM is turned off. I therefore decided to immediately short the low-side MOSFET (CH1N) to groun...
In the linker script provided by STM for STM32G474RETx, the memory section is:MEMORY { CCMSRAM (xrw) : ORIGIN = 0x10000000, LENGTH = 32K RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K FLASH (rx) : ORIGIN = 0x8000000, ...
I'm using an ov2640 camera.When I use HAL_DCMI_Start_DMA(&hdcmi, DCMI_MODE_CONTINUOUS, (uint32_t)camBuf0, (CAM_W * CAM_H) / 2);, HAL_DCMI_FrameEventCallback is called,but when I use HAL_DCMI_Start_DMA(&hdcmi, DCMI_MODE_SNAPSHOT, (uint32_t)camBuf0, (...
Hi,I have a custom board with an STM32L031C6 and I'm trying to read the internal temperature. The board is battery powered at about 2.6V and the vdda is the same.If I read the ADC channel with vrefint, it returns a value of about 850, which, when pas...
