We are using the RHFACT04 gate. In a fault-mode, where the path between an external driver and this receiver is broken, the input will be pulled down by a 10k resistor. At maximum input capacitance this violates the DSCC of 0 - 8ns/V slew on the inpu...
Dear ST community. I am new to this forum and am not a programmer. Hoping someone maybe able to help with an issue.I have a unique invention that can advance a number of industries which uses MEMs motion sensors and allows a computer to become much m...
Hi All,I'm a newbie at STM32 device. Now, I have STM32L433 and I would like to try CAN loopback mode at my device. Does anyone can help me out? It does not work. Please check the attachment. Thanks.
I'm using the BLE_SensorDemo Atollic project from BlueNRG DK v3.2.1 as the starting point for a custom application. Is it possible to rename the name of the Atollic project?I've done so by searching for all plain-text references to the old project na...
Hello!I'm developing BlueNRG-1 application, I want to add the OTA functionality to my project. But when I flash default OTA Service Manager to empty device it disconnects from ST-Link Utility and can't connect again. The only way to flash again is to...
Hello guys. I am trying to drive an audio DAC(PCM1774RGPR) using I2S protocol with STM32H750, and I found that the I2S Master Clock output is disabled due to conflict with LTDC pins. I also found that the DAC requires a SCKI input, which I think that...
Posted on February 13, 2017 at 20:17Hello everyone.I've been working for a long time with SPBTLE-RF modules in our project. I never experienced any problems with these modules.But now we've redesigned our PCB and are going to use BlueNRG-MS chips di...
