MIMXRT1062 Bare MCU (Teensyduino)

## Embedded Firmware Engineer — MIMXRT1062 Bare MCU (Teensyduino) ### Project Overview I have designed a custom PCB featuring the NXP MIMXRT1062DVJ6B microcontroller. The board includes an MKL02 USB bootloader chip (Teensy 4.x pre-programmed bootloader, v1.09) and will be programmed using Teensyduino (Arduino IDE). The schematic will be shared at the start of the project. --- ### Scope of Work Please deliver **one** of the following two options — choose whichever you have experience with: **Option A — CAN Bus (FLEXCAN)** - Initialize the MIMXRT1062 FLEXCAN module within the Teensyduino environment - IOMUX pin assignment and CCM clock gating configuration for TX/RX pins - Basic message send and receive (loopback or verified with 2 nodes) - Baud rate configuration at 500 kbps or 1 Mbps -GPIO_AD_B0_02 - CAN_TX -GPIO_AD_B0_03 - CAN_RX **Option B — PWM (FlexPWM / QuadTimer)** - Initialize the MIMXRT1062 FlexPWM or QuadTimer module within the Teensyduino environment - IOMUX pin assignment and CCM clock gating configuration for the relevant pins - PWM output with configurable frequency and duty cycle - Basic test code (e.g. LED dimming or servo signal) -GPIO_EMC_31 - pwm1 -GPIO_EMC_36- pwm2 --- ### Deliverables - Working firmware that compiles in Teensyduino and uploads via the MKL02 bootloader - Brief documentation: which pin maps to which function and how to use it --- ### Candidate Requirements - Hands-on experience with NXP i.MX RT1060/1062 or Teensy 4.x - Register-level knowledge of IOMUXC and CCM https://www.pjrc.com/store/teensy40.html
