Hi, I am struggling to figure out how to setup this configuration with an MQTT client running with freeRTOS, using the integrated ethernet MAC and with MbedTLS. I am using mikroC PRO for ARM v.6.2.0
Any hint or help would be appreciated

Hello. I am looking for a library to decrypt my electric energy meter's data. I found some code for Arduino, but it uses/includes AESh and GCM.h. In addition, I am using only Microchip PIC controllers + mikroPascal PRO for PIC, so what I found is almost useless to me.
I foind a "Crypto library", but this poor package manager is not installing it properly, nor do I know if this library is correctly working at all (the author doesn't respond and his last login here was 10 years ago).
If somebody could help, please?
The Energy Meter is LANDIS & GYR E450, It sends out one data block every 5 seconds through its User interface (M-BUS). I already built an electric interface module (converter to TTL serial level), but I stuck with decryption.
Thank you.

Hey,
I'm programming a MCU PIC32MX530F128L with CAN library provided in MikroC. But it doesn't work and I don't know why.
After reset, the ship stops when it reaches the function CAN1Initialize().
Is this library has been tested with this chip ?
Than you for your help.

Hi All,
I need to establish a bridge that will sit between a router and a PC which will log the IP addresses of all traffic that pass between (including TCP and UDP). It should also restrict some IP addresses, acting like a very basic firewall.
The speed at which it does this is not important as the PC only runs dedicated software.
The connection can either be wired (via 2x ethernet ports) or wireless (one wireless device connects to the router's wifi whilst a second provides a network for the PC to connect with). Ideally the solution could accommodate both.
I am developing using the Fusion v7 and PIC32MX795F512L and have 2x ethernet clicks with 2x wifi clicks on order.
I have explored:
- using the Mikroe libraries to speak to both (1) the internal ethernet port and (2) an ethernet click port but cannot figure out how to bridge the traffic using Mikroe libraries. I am told that the libraries accommodate one port max so using both the internal and an external port seems like a possible solution.
- Github/other forums to seek example code that may help to speak to the ENC28J60 (IC on the ethernet click) directly but refs seems incompatible with MicroC.
- Review of some libraries available here that deal with the wifi click. Assuming the libraries are unable to accommodate more than one wifi click like the ethernet click libraries, this seems like an unlikely solution.
- Mikroe support.
I wonder if anyone has achieved a basic bridge like this for a firewall, range-extender or another similar application and if anyone can provide any example projects or code.
We have achieved this using the raspberry pi but wish to establish a professional solution using PIC and Mikroe.
Any help or advice would be appreciated.
Thanks for your time and all the best.
Alex
