We have developed a Sigfox circuit board using the SAMD21 and a sigfox module. Although this is a standalone board we are using the Arduino bootloader (the Arduino M0 using the SAMD21 chip) as some of our libraries were previously developed for the ATMEGA328 and we want to reuse those. We would like to get the power consumption down very low (the application note says that with the RTC we should get 10uA in sleep) so we can run off battery. Currently, this is higher and is because of the way the arduino boot loader initialises some of the registers. We have made some clock and peripheral adjustments but are not getting to the level of power expected. We are looking for someone who has had experience with SAMD21 who can give us a block of code which turns off all the unnecessary clocks/ peripherals which we can embed in our code. We need the RTC in sleep mode to wake up the chip periodically to send the sigfox message and we need an external interrupt which when it fires we increment a counter. If you would be able to do this please let me know. We can discuss further. Please indicate if you have experience with the SAMD21 specifically and with the low power sleep mode. To verify the project we would take the code and using the Arduino IDE flash the firmware to our custom PCB. We would then measure the current using in sleep mode.

Dear Sir, We are a small R & D company, based in Bulgaria, Europe. We specialize in developing Embed systems based ST(STM32), Microchip (Atmel )(PICs,AVR,Atmel ARM) and TI (MSP430) MCPUs and peripheries. We realize projects with requirements similar to yours based SAMD21(with peripherals). For realized our low power project (SAMD21) we use Atmel Studio 7 or IAR EWARM IDE. We think Arduino IDE not effective for control low power mode(sleep mode). If we receive more information about your project, we will give you a real cost and time to implement your project. We based in Europe, not customs problems for delivery models and samples for testing Best Valeri T.

Dear Client I would like to say this is my fortune to show you my hardware skills. I can bring your idea to live and you can reach the goal absolutely with me. I have 10+ years experience in hardware design(schematic design, PCB design...). My develop tool is Altium Designer, CADENCE. I have designed many high speed devices in embedded system. My recent design is AM5728 Core Board.(quad-core, 1.5GHz, DDR3 4G, EMMC 32G, Gigaethernet, usb3.0,...). And another is PCIe v2.0 to ethernet(or usb3.1) convertor. All design is passed in serveral EMC tests. I have designed MEMS tracking board, ultrasonic distance measurement. My design is very stable in industrial environments. I think your design is not difficult. but most important thing is EMI, EMC. I have been working main hardware developer in large scale industry product company. Designing the PRODUCT is very different form desigining the general pcb(test board, kit,...) You can feel everything what is my real skills in hardware development. Look forward to working with you for a long time. Thanks! Hope to see you soon

Hello. Thank you for inviting us to bid on your project. We have read the description, and it sound like a challenge, but we need to discuss more. We never used a SAMD21 controller before but according to the datasheet it has low power modes (idle and standby also sleepwalking peripherals). Feel free to open a chat so we can discuss more. Best regards, Protocoders

TL;DR: Just as a proof of commitment, I could give you an initial binary for you to test in a couple of days, free of charge. Read further, if interested. Good day. I have plenty of experience designing MCU-based embedded systems. I've worked at Freescale Semiconductors for half a decade as an engineer. I've worked with several arm-based microcontrollers (NXP, Atmel (now Microchip) and STs families) and, lately, with the esp8266 and esp32 family of microcontrollers, either with or without an RTOS. I have designed similar projects before, designing firmware and bootloaders for MCU-based systems, so I have plenty of ARM cortex-M code available which can be adjusted to your particular requirements. I estimate that in the stated time we could have a final prototype, taking into account a long enough testing phase. Regarding payment,of course, none is required before a proof of work (PCB design ,schematics and other related documentation). I'd find quite useful for the both of us, if you'd find the time to talk a bit further regarding your project's requirements. No strings attached.

Hello We have been an engineer for more than 8 years in the market and have already developed projects for several companies using microcontrollers like ARM, PIC, AVR, NXP, Nordic, Texas, STM, ESP, Arduino, Raspberry among others. Using the general description of your project is possible to make a generic estimate, but the refinement of the total amount of work and the value of it will depend very much on the quantity and complexity of the features to be implemented, so I look forward to your contact for more details. Thank you.
