Hi, We need help from electronics hardware and firmware designers who have worked on DSPs before because device on which we are working is based on signal processing. Further details will be shared with selected freelancers only. Thanks.
Hi Ajai. How are you? Everything is fine? I was able to transmit data via uart to the LIZARD card and view it in the display. I can share with you everything I've done so far. The software and hardware connections. I would need (via UART) the ability to update the firmware and / or external flash. Are you willing to do this job for me? Best regards Domenico

Also want to make some changes to the firmware. Mcu is PIC16F18875 Would like someone to load my firmware and just see if they get any errors when compiling
We have a pcb deisng with firmware that works quite well, we would like to add a couple of features (additional input contact and ntc reading) and so a redesign and a firmware change is required. We need a development company with a lot of experience with pcb design and atmel platform. No prototype needed, we will take care of that. Please begin you bid with atmel, to be sure you read the above. Otherwise your bid will not be considered. Many thanks

Hi! We want to test our mobile app on iOs. To participate, you need actual versions of iOs (not older than 1 year). Also, for the last part of the manual test you should prepare a second phone, that may be on the Android platform with actual firmware (not older than 1 year). !! Get ready to record your phone screen and your voice. Full step-by-step instructions is here:
Beacon and Loudspeaker - details will be provided after the NDA is signed for the selected candidate.
We have many simple modules to design like temperature sensor or LED drivers. For each module, you must select the key components and produce schematics and layout in Altium. You must also provide a basic Arduino firmware for basic interactions with the module. The jobs will be awarded on a per module basis but ideally the same person would end up making most of them. You must be experienced with Arduino and Altium.
We are currently in the in the process of updating the firmware of our industrial instruments so the instrument screens display new information. The problem is that we have lost the original designs for the screens and only now have the .bmp files. We need the .bmp files edited with the new text information, converted back to .bmp format so that we can integrate them into the updated firmware. I have attached the .bmp instrument screens as well as the examples of what text we need changed. For example: OMNIA Boot Up Screen_320x240 - is the current boot up screen of the instrument. OMNIA_change_to is the text we want to change it to I have attached images for multiple screens that need changing and converted to .bmp files.
Hello there, We "successfully" ported the android firmware to our device, from Android 9 OS to Android 9 TV OS. Image boots, but we have some loose functionalities. No sounds, no display settings, IR remote not working, google voice search not working, etc. Is there anyone that has experience with android os that could help us? We only have the firmware images *.img, as our previous developer disappear.
we are looking to develop an AC induction motor controller to deliver 350–800A of output at 24–96V system voltage. This project would involve hardware and firmware development.
I need someone to write embedded code in a Microchip PIC16F15243. The design includes a MEMS accelerometer and magnetometer that communicates with the uC vis I2C. The uC will need to process the signals from the accelerometer and magnetometer. The processing is relatively simple, a threshold above the baseline level. The device will operate on AA batteries so the uC and sensors will need to go in and out of sleep mode.
We got a new pcb made and need a new firmware for it…… old firmware can be used as a guid 80 percent done just need to add some things and also move some things from one pin to another. Using Microchip PIC16F18875 also may want to change the mcu to something elce as it is now out of stock for future boards!

we need to modify the firmware of the GL-x300B collie router, so that if it is reset to factory, the configurations previously made in the firmware will not be modified, i.e. modify the factory SSID for one of our own and after physically resetting it, this will be maintained. The router supports openwrt

Hello, My team redesigned the ESP32 TouchDown board () in order to fit our needs. Mostly in terms of size and removing some unused parts. So right now we have our own hardware (ESP32 pcb board + touchscreen display, same as TouchDown project) and it was tested with TouchDown firmware, everything seems to work. We are looking for someone on the software side to help integrate our design (user interface) to the ESP32. Please see the images attached. The buttons have different states: 1. disconnected (gray, not lit up) 2. connected (white, lit up) 3. pressed / pressed & active state 1 (purple button) 4. pressed & active state 2 (green button) Thank you! Best, Marius
Hello Badi, I've talked with several FCC test labs and they told me that they need to test the Low/Medium/High frequency level for the gamepad PCB. They also told me that the nRF52832 has a "Direct Test Mode", or DTM function that can be activated through firmware. I would like to start a contract to find this DTM function and implement it into the current gamepad firmware so I can present it to the FCC testing labs. Thank you
