Firmware Jobs

Please apply only if you have experience in this type of work. This is a remote project for technicians who has had exposure to CMOS or CCD/PRISM/LED/ sensor systems, and have the capability to build the sensor assembly. We are a startup company looking at building a Refractometer Sensor Assembly (3 sensor assemblies for our prototype). The sensor will be integrated with a PCB, which will have other sensors. The purpose of the sensor assembly is to converts the refractive index of a food sample to % brix. OUR SPECS are as follows: The sensor assembly - must not exceed 20mm x 25 mm x 15mm in size - CMOS or CCD sensor - Triangular prism (see picture) - LED wavelength of about 600nm OTHER SPECS - 0 - 20 degree brix minimum - Precision ±0.1%; - Resolution 0.05% - Output Method: Dig...

I need help with firmware development for my project using Nordic Semiconductor's nRF52 Series. The primary function of the firmware is communication through BLE and NFC. Therefore, I am looking for someone with experience in developing firmware for wireless communication. The preferred programming language for the firmware is C. The ideal candidate will have experience in: - Developing firmware for Nordic Semiconductor products, specifically the nRF52 Series - Working with BLE and NFC communication protocols - Proficient in C programming language.

I need firmware development for ESP32-C3 for following tasks: -Ultra low power consumption design -Run on 2xAA batteries for more than a year -On-board Digital Temperature Sensor value reading and logging (logging period) -Sending to an MQTT broker (upload period) -Wait for commands from server after data upload -Wi-Fi parameter (SSID, passwd) set over BLE for lower power consumption -Data encryption -no webpage hosting or accesspoint mode needed Those are the main functions of the device. We need an experience for low power programming, we are able to design the circuit.
