STM32WB55RGV6 BLE design questions
Several BLE circuit design inquiries of the STM32WB55RG MCU.The BLE impedance requirement of this MCU is 50 ohm, and it is recommended to use LPF (MLPF-WB55-01E3). For the detailed circuit diagram, please refer to the fourth page of the attached file...
Resolved! STM32WB55 GPIO alternative SPI2(GPIO_AF3_SP2 vs GPIO_AF5_SPI2).
STM32WB55RGV6 connects ADS1299 by spi. And I choose spi2. There are three signas miso\ mosi and sck. SPI2 has two alternative: GPIO_AF3_SP2 and GPIO_AF5_SPI2.① STM32CUBEMX automatically generated miso(GPIO_AF3_SP2), mosi and sck(GPIO_AF5_SPI2).Initi...
Problems with time server and STM32CubeIDE debugging
I was trying to use the time server for a project on STM32WB55. I tried to use it in an empty project. When I tried to debug, this window pops up:The curious part of the problem is that this error seems to happen with the time cluster only: using ano...
Resolved! STM32CubeMX generate "feature not supported" instead ...
The STM32CubeMX generate:```#define LCD_SPI_Send_DMA(rd, ln) BSP_ERROR_FEATURE_NOT_SUPPORTED```instead if I modify the generated DISPLAY/Target/lcd_conf.h with`#define LCD_SPI_Send_DMA BSP_SPI1_Send_DMA`seems work correctly.I am using:Nucle...
STM32: consumption due to I2C in stop2 mode
Hi, I use the nucleoWL (STM32WL which is based on STM32L4). I want to use LPWAN to communicate some measurements each day. I use I2C between MCU and sensors. If I try the Sigfox Push Button exemple, I have 2uA in stop2 mode but if I add I2C1 (thanks ...
HAL_I2C hangs when it enters I2C_WaitOnFlagUntilTimeout() function.
I'm using verion 1.1.5 of the I-CUBE-LRWAN software and reading a few I2C sensors using the HAL_I2C functions. No issues when sensors are functioning properly; however, I have run into periodic sensor failure issues while testing, either permanent or...
Resolved! Restore ST-Link Connection on B-L072Z-LRWAN1
In order to achieve minimum power drain on the B-L072Z-LRWAN1 discovery board, it is necessary to remove some solder bridgesSee: https://community.st.com/s/question/0D50X00009XkbSOSAZ/excess-current-consumption-running-bl072zlrwan1-from-batteryAnd:ht...
Resolved! Cant power B-L072Z-LRWAN1 with battery
We recently received our B-L072Z-LRWAN1 but are not able to run the program while batteries are plugged in. In the datasheet it says that we need to remove SB37 to accomplish this. But then I cant program it anymore? How can I use the board with batt...
Resolved! Excess Current Consumption Running B-L072Z-LRWAN1 From Battery??
Posted on December 11, 2017 at 20:21 I have removed all the solder bridges & links to minimise stray consumption. When I measure the combined current through JP3 and JP1 (ie, MCU & RF), it is ~0.87mA between Tx pulses. (SB19,14,17 are removed; JP2...
