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...
Resolved! How to include DSP Filtering Functions?
In the last month, I did an example of FFT using the CMSIS DSP library. Now, I am trying to design a simple "matched filter". In my code I am using "arm_fir_init_f32" and "arm_fir_f32". While debugging, on the line of "arm_fir_f32", I am getting "H...
How implement BLE client multiconnection with WB55?
Good time of day!I am facing some problems with testing example app (BLE_p2pRoteur on WB55.Nucleo board).First one board flashed as a client, 3 others as a servers, Server 1 to 3 are defined in app_conf.h file, corresponding appplication numbers in m...
Resolved! COMP1 input pin change from PB4 to PB2 after init not working. STM32LWE5CCU6
I have two independent oscillations one in PB4 and the other on PB2.I start the first oscillation on PB4 and comp returns the oscillation picks correct.After without stop the COMP1 i change the input plus pin from PB4 to PB2. Using MODIFY_REG(COMP1->...
Resolved! B-L072Z-LRWAN1: Is there a second I2C bus?
Is there a second I2C bus exposed in CMWX1ZZABZ besides I2C1 pins 35&36?I would rather use second I2C than adding MUX to get all sensors connected.Thanks,Tipo
