Hi , I recently acquired an ST4SIM-300M eSIM and I am unsure how the ST4SIM-300M should be activated initially.I also watched your video about Remote SIM Provisioning using the Motive eSIM Secure Connect portal, and I would like to ask whether the ac...
The function of the PERS_RX flag in PROTOCOL 0 is described as: '1: enable the persistent RX mode.' What does that actually mean/do? I couldn't see any explanations in the rev. 13 data sheet for the S2-LP.
Hi, Here i post a driver for SSD1306 128X64 Oled Display. You must enable I2C configuration void I2C_ConfigurationMaster(void) { GPIO_InitType GPIO_InitStructure; I2C_InitType I2C_InitStruct; /* Enable I2C and GPIO clocks */ if ((I2C_Type*) SDK_...
How is the best configuration for setting MTF as free-running timer ?void MFT_Configuration() { MFT_InitType timer_init; NVIC_InitType NVIC_InitStructure; SysCtrl_PeripheralClockCmd(CLOCK_PERIPH_MTFX1, ENABLE); /* Init MFT1 in mode 2 */...
Hi, I'm trying to create a project to display data on an OLED screen. Even before programming my screen, upon simple connection, the connection constantly drops, and I can't maintain a stable link. I don't know where the idle setting is located in th...
Hi all,I'm trying to create a project to read a temperature sound like a DS18B20. The problem is that I need a precise and stable delay time. Using Systick isn't possible because there's a conflict when using BLE. I tried using an MFT, but I can't cr...
On ST87M01 current version 2.7.0 I suspect that everything that goes in module via "AT" interface passes through filter which removes spaces and sets everything lowercase. This is OK for AT commands, but it mingles with user data that is passed, for ...
Hi, I can't read 40bit with my BlueNRG-1 and help wit timer in free-running. My us is ok but when i tried to read, it stop before read all 40 bits. Here i post my driver dht11. In main for test uint8_t h, t; if (DHT11_Read(&h, &t)) { printf("Hum...
Hi all,I was super exited to test the new STUSB4531 IC on the EVAL-SCS006V1.The PPS support of the chip is the main reason to pass over from the STUSB4500. I have done a lot of test with 100W PPS enabled USB-C supply but without luck. i did not manag...
