SAME54 I2C Driver Issue Solved embedded by blog_1buq8n - September 10, 2019October 10, 20190 If you are reading this post that means you are using ATMEL or Microchip controller. We are using ATSAME54 micro from microchip, it is ARM based cortex-M4 series controller. In our application we have around eight I2C ( Inter-integrated Circuit) slave devices connected. I2C slave devices includes, RTC, onboard temperature sensor, FRAM, LED drivers etc. Well as you know all I2C slave devices can be addressed using their addresses. Well as most of guys does we too have downloaded sample code from start.atmel.com and tested. We have SAME54 explained pro and we brought PCA9685 LED driver. This is simple I2C based LED driver and is easily available, its schematic and design also available from adafruit. With sample code and its
Modbus Master Stack On ATSAME54 With RTOS embedded by neudeep - September 7, 2019September 7, 20190 In previous post we discussed about how to port modbus slave stack on ATSAME54. This post we will discuss on how to port modbus master stack on SAME microcontroller. You can download example freemodbus master stack for reference from FreeModbus. We have referred the 'AT91SAM7X_FREETROS' example project. You can follow the steps from previous post for creating directory of project files. Instead of modbus slave stack, add modbus master stack. In addition, We are using FreeRTOS in our project. So In top level directory we have added FreeRTOS V9.0.0 . Please refer to modifications in port specific files described in previous post. So lets begin with issues while port modbus master stack on SAME, Without an operating systems there are
