Resolved! Is it true that STM32WLE5 (UFBGA73) UART programming is over pin E5 (TX) and C8 (RX)?
Application note AN2606, on page 380. It says that in the default bootloader, USART is used on pin PA9 (E5)(TX) and PA10 (C8)(RX). However, when I select USART1 in STM32CubeMX, in mode Asynchronous, pins E1 (TX) and C3 (RX) are used. USART programmin...
Resolved! Bare metal SPI DMA initialization problem on STM32WLE5
Hi all, I'm trying to implement SPI TX communication with DMA. The following "prepareDMASPI()" function should configure and start DMA transferts from a buffer to the SPI device. But it doesn't work (No spi clock or MOSI data), although the SPI is pr...
STM32WL LoRa and Sigfox in one application ?
Hi everyone,I am currently working on the STM32WL55JC, I am using the stm32cubewl_v1-1-0 for doing a LoRa application and a Sigfox application using the provided examples. I would like to know if there are any limitations (Hardware and/or software) f...
STM32WB55 ADC Single scan (A/D9, A/D9, A/D10), using DMA AND LPTimer --- not seeing any values?
Good afternoon....Trying to trigger scan mode (2 channels but 3 conversions ---- A/D 9, A/D 9, A/D 10) via software trigger that is called in the LPTIMER (I do not have access to other timers bcz they are tied up in other code that is why I am not us...
Resolved! How do the Stm32wl55 SubGHz_Phy Radio driver PA Config Settings conform to AN5457 section 5.1.2?
Hi,we are working on an own hardware design with the STM32WL55.According to AN5457, section 5.1.2, I am supposed to select a Power mode (Low or High), and then a maximum output power for which I would want to optimize my design. With that maximum out...
(STM32WL55JC) Is it possible to expand flash or RAM in order to fit my project on this board? If so, what is the most straight forward, feasible way?
My project involves LoRaWAN communication and embedded machine learning. we've trained a basic model which fits in flash memory, but barely. As our data set grows and our model becomes smarter, I imagine we will need more space. As of right now, our ...
ADC 2nd channel is bouncing all over the place (stm32wb55)??
I am running a scan mode of AD9 and AD10. I use a timer to generate an interrupt every 15ms....Inside this IRQ I start an ADC conversion scan.....After each conversion I store the value into an array. I have a potentiometer hooked up to adcValue[0] ....
Non working USB CDC after LL_C1_IPCC_SetFlag_CHx(IPCC, HW_IPCC_SYSTEM_CMD_RSP_CHANNEL); call on STM32WB5MMGH6TR
Hi,I have a problem with USB CDC on STM32WB, after calling LL_C1_IPCC_SetFlag_CHx(IPCC, HW_IPCC_SYSTEM_CMD_RSP_CHANNEL). The USB stops working. Data cannot be sent or received via USB and also the USB IRQ is not working. The USB does not work also af...
