Off-the-shelf GNSS receiver modules like new Teseo-LIV3F makes sense for application developers without any advanced software requirements and without too much RF expertise. In this case people can achieve fast results and avoid hassle compared to a ...
Hello,I am using the BlueNRG 1 stack V2.5.0.I am using the callaci_gatt_add_char(SeviceHandle, UUID_TYPE_128, &char_uuid, 20, CHAR_PROP_READ | CHAR_PROP_NOTIFY, ATTR_PERMISSION_NONE, 0, 7, 1, &CharHandle);But I am seeing that I don't always see the ...
Hello,I want to connect a muxed PSRAM (ref: W956D6KBKX) with STM32L4S5VIT in LQFP100 package, The PSRAM requires IO signals at 1.8V. and in the MCU tension is fixed at 3.3V.So is it advisable to use level translators to convert the IO signals from 3....
I am using a BlueNRG-LP and started with the CCA01M1 I2S project. I changed the callback so that it applies a volume to the stream in real time. But this seems to block the code if I use a double (which id like to do to see some precision - and I wan...
