QUESTION 15 OF 30

What programming languages have you used to write firmware?

Contemporary firmware engineers must be familiar with a wide range of programming languages. Originally, firmware was written in low-level languages such as C or assembly code. However, many types of firmware are now written in higher-level languages such as JavaScript, Ruby, or Perl. While there is no right or wrong answer to this question, your research should indicate the types of programming languages the organization prefers. If possible, include these in your answer.

"Early in my career, most of the firmware I wrote was either in C or basic assembly code. This was sufficient because the code was then assembled into machine code which the hardware would access during start-up. However, with the proliferation of firmware into a wider variety of devices and appliances, I am now writing code using higher-level languages such as JavaScript, C, Ruby, and Pearl. These are more efficient and enable me to create code specific to the device and its functions."
