I recently got a new custom PCB with a STM32L476RGT6 and a BlueNRG-M2SP. I have a Nucleo L476RG and a X-NUCLEO-BNRG2A1 to test and make sure the program works. I am running the SensorDemo_BLESensor-App project from the X-CUBE-BLE2 package, and it wor...
Hi all,I am designing a 48 volt to 12 volt 3 amp DCDC asynchronous buck converter (with frequency > 200kHz) and I found the L7987. Although it says asynchronous in the datasheet, it looks like synchronous in the block diagram. I am confused, can some...
Hello,I’m building a custom communication protocol using STM32 (F1 series) as a relay-only device, sitting between an ESP32F103C6T6A and multiple slave ESP32F103C6T6As.The ESP handles all frame dispatching and reception. The STM32 "master" is just an...
Hello everyone.I'm currently building a controller for this energy measurement chip.So far, I've built my controller and can perform a remote reset and read data, but when I want to configure a register, I send my desired configuration, but when I re...
I am working on a Tire Pressure Monitoring System (TPMS) application. This is not a device that goes inside of a tire. This will be a device that talks to the TPMS devices inside the tire. I found the SPIRIT1 as a good choice for sub 1 Ghz wireless r...
Hi everyone, I am new for STUSB4710A. I connect STUSB4710a STEVAL_ISC004v1 evaluation board to my laptop, through a min b usb cable. when I run the graphic interface en.stsw-stusb001, there is one error: usb error: no target found. please connect fir...
Hi everyone, I met a problem when I measured the current rms value with stpm33 ic.I'm using this IC with resistive loads and other load profiles with low crest factor. But I met a case with a high crest factor load like as SMPS type loads. I collecte...
Hi,I'm facing an I2C communication issue between an STM32F107RCT6 microcontroller and the MAX11612EUA ADC. I created a clean project in STM32CubeMX using HAL library v1.1.9.0. I'm using HAL_I2C_Master_Receive_IT() to read data, and in the callback I ...
Hi,How can I capture packets in my mesh on BlueNRG-2 module? How can I know if a module has passed any package to another module? I see packets directed to a specific module, but I don't see being an intermediary in the network.Regards Adam
I'm trying to develop a multiprotocol board with Dual Stack wM-Bus + NB-IOT. I found this link:https://www.st.com/en/wireless-connectivity/nb-iot-products.html So the ST87M01 module is capable of it. I have the next questions:1) The module is sold wi...
