QSPI interface for LCD display @ nRF52 series
Following up to the blog LCD demo 320x240 @ nRF52840, I would like to describe how to use the QSPI interface to drive the bigger LCD display such as 360 x 360 resolution @ nRF52840. QSPI Quad Serial Peripheral Interface The QSPI peripheral provides support for communicating with an external flash memory device using SPI.… Continue reading QSPI interface for LCD display @ nRF52 series
Advanced UART Driver (LibUARTE) on Nordic nRF5 SDK
This blog is to describe some data flow on the libuarte which is under the nRF5 SDK. As the below, you can find the libuarte events on difference receive mode. The official production release of the libuarte has released since SDK 16.0 or later. For example, you set the libuarte DMA buffer to 255. There… Continue reading Advanced UART Driver (LibUARTE) on Nordic nRF5 SDK
AT Commands on the Nordic nRF9160
This blog is to prepare the most common AT commands on nRF9160 and I will try to show how to use the at_client with link monitor for connecting the network. https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/at_version.html Modem firmware versions This document describes AT commands used in all versions of the nRF91 Series modem firmware. The modem firmware versions that support… Continue reading AT Commands on the Nordic nRF9160
Format of IntelHex
Intel hexadecimal object file format, Intel hex format or Intellec Hex is a file format that conveys binary information in ASCII text form. It is commonly used for programming microcontrollers, EPROMs, and other types of programmable logic devices. In a typical application, a compiler or assembler converts a program's source code (such as in C… Continue reading Format of IntelHex
Byte manipulation on Python platform
This blog is to share some demo or guideline how to work the embedded byte operation on python. For example, if you are using the PYSERIAL module (UART) and communicate with external MCU, you need to know how to put or extract the byte data through UART python module. Here are some blogs to describe… Continue reading Byte manipulation on Python platform
How to add the timestamp on the nRF5 Log module
This blog describes how to enable the timestamp on the nRF5 SDK log module. For example, it is the example to get the timestamp with log for the BLE scanning. You need to enable sdk_config.h. Enable the NRF_LOG_USERS_TIMESTAMP in this case. Also, you need to create the additional app_timer and start it.
How to support the UTF8 on the Segger Embedded Studio
This blog is to describe how to configure the Segger Embedded Studio to support the UTF8 coding inside its IDE. What is UTF-8? UTF-8 is a variable-width character encoding used for electronic communication. Defined by the Unicode Standard, the name is derived from Unicode (or Universal Coded Character Set) Transformation Format – 8-bit. UTF-8 is capable of encoding all 1,112,064 valid character code points in Unicode using one… Continue reading How to support the UTF8 on the Segger Embedded Studio
